Posso personalizar a posição dos títulos em tikz
groupplot
s? No exemplo a seguir, gostaria de colocar os títulos (a, b, c e d) dentro de axis
(próximo ao canto superior esquerdo).
\documentclass{article}
\usepackage{xcolor}
\usepackage{graphicx}
\usepackage{pgfplots}
\usepackage{amsmath}
\usetikzlibrary{pgfplots.groupplots}
\begin{document}
\begin{tikzpicture}
\begin{groupplot}[
group style={
group name=my plots,
group size=4 by 1,
ylabels at=edge left
},
%footnotesize,
%width=3cm,
%height=7cm,
ticks = none,
tickpos=left,
ytick align=outside,
xtick align=outside,
enlarge x limits=false,
xlabel=$t$,
ylabel = $y$,
y tick label style={
/pgf/number format/.cd,
fixed,
fixed zerofill,
precision=2,
/tikz/.cd},
max space between ticks=2500pt,
xmin = -.5,
xmax = 10,
ymin = -.5,
ymax = 5,
]
\nextgroupplot[title=(a)]
\addplot[domain=0:2] {1};
\draw (axis cs:2,1) -- (axis cs:2,3.5) -- (axis cs: 5,3.5) -- (axis cs: 5,1);
\addplot[domain=5:10] {1};
\nextgroupplot[title=(b)]
\addplot[domain=0:2] {1};
\addplot[domain=2:6,smooth] {-.65*(x - 2)*(x - 6) + 1};
\addplot[domain=6:10] {1};
\nextgroupplot[title=(c)]
\addplot[domain=0:2] {1};
\draw (axis cs:2,1) -- (axis cs: 4.5,4) -- (axis cs:7,1);
\addplot[domain = 7:10] {1};
\nextgroupplot[title=(d)]
\draw[->] (axis cs:0,1) -- (axis cs:2.9,1) -- (axis cs:3,4.5) -- (axis cs: 3.1,1) -- (axis cs:10,1);
\end{groupplot}
\end{tikzpicture}
\end{document}

Colocarei aqui a resposta do @ignasi, pois ele a adicionou como comentário.
Use \pgfplotsset{every axis title/.append style={at={(0.1,0.8)}}}
onde você pode ajustar a posição do rótulo alterando as frações.
